Drinkers don’t deserve customer support

I would appreciate it if SAB valued their drunk customers and respond to customers complaints. I often find empty sealed beer cans in my purchases and it’s ******* to drink and drive to the store using petrol which costs more than a can for me to lay a complaint the store is not accountable to. It is a breach of contract for me to pay for a service I do not receive. I have sent email complaints but have been ignored. I would probably get drunk and forget about it? The thing is that people budget for alcohol like it’s a necessity and if I don’t have money SAB won’t loan me alcohol in good faith, so why am I buying empty cans?
